More rpm means more fuel injections but it also means injections of less fuel per injection, it also means less boost, and less TERS recovery and less power per injection. They use the same amount of fuel regardless of RPM above 10.5k rpm point blank period.mwillems wrote: ↑10 Apr 2017, 19:50I'm not sure they'd start with less fuel. Wouldn't they do less fuel saving and go faster, with the same fuel?ENGINE TUNER wrote: ↑10 Apr 2017, 17:28These engines use the same amount of fuel regardless the rpm over 10.5k rpm, so the only reason running above the optimal rev range would increase fuel consumption is because of the lower power being produced and so the longer throttle times and time down the straight.harjan wrote: ↑10 Apr 2017, 11:13Running them above optimal rev range is primarily a bad influence on fuel consumption. I expect these these engines to have a relatively flat torque line, so power wise there isn't much to be won by running them in correct range.
It's good to see the chassis is class A- if they can find 75-100 bhp they're in the top 6.
There is plenty of power to be gained by running in the correct range, as well as lower overall fuel consumption, as well as increased harvesting, as well as a lower starting weight on the start grid from using less fuel over the course of the race, Which then leads to improved tire wear and maybe even smaller brakes or less brake cooling, etc, etc, etc. It constantly compounds itself.
Also, if they are on a long straight and going into higher revs to get that last little bit of speed, surely they would be using more fuel at that point, not regardless of the RPM? More revolutions means more fuel injections, no?
The fuel max is 100kg/hr above 10.5k rpm regardless of rpm, load, speed, boost, temperature, elevation, hair color, toe length or whatever other variable you want to measure.
If they were making more power they wouldn't have to fuel save(Merc and Ferrari are barely doing any fuel saving) so they would underfuel to make them faster over the course of the race.
More fuel does not make you faster in this formula, only more power(with the same fuel) or more power with less fuel.
